DOMESTIC-BOILER CIRC ULATOR Specification of Letters Patent.

Application filed March 28, 1919.. Serial No. 285,838.

To all whom it ma: concern Be it known t iat I, FRED G. Koran, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Domestic-Boiler Oirculators, ofwhich the following is a specification.

The invention relates to means for providing hot water for domestic use and adapted more particularly for positively circulating the water in a domestic boiler so that economy results inthe consumption of fuel and means is provided for readily removing sediment from the boiler.

The invention consists of a device adapted to be attached to thebottom of a boiler such as commonly used in connection with a kitchen range whereby to enable the water in the boiler to be heated in a manner so that hot water may be obtained in a comparatively short time after the heater is started and without requiring the heating of all the water in the boiler.

The drawingsillustrate a preferred embodiment of the invention. However, it is to be understood that in adapting the same to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the inventio as claimed hereinafter.

Referring to the drawings,

Figure 1 is a view in elevation of a domestic boiler provided with a water circulator embodying the invention, a portion of the lower part of the boiler being broken away to show more clearly the relation of the attachment. I

Fig. 2 is a view on the line 2-2 of Fig. 1 looking upward, the part being shown on a larger scale.

Fig. 3 is a sectional-detailon the line 33 of Fig. 2.

' Fig. 4 is a modification adapted to form a stand for the boiler, the 'circulator, burner and boiler being in section.

Fig. 5 is a plan view of the modified form of cireulator, a portion of the top being broken away. j

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

The device is essentially a one-piece casting and comprises a hollow body 1 which is -and the other to receive a of circular outline and comparatively shal- Patented Mar. 9, 1920.

low, the upper wall or top being convex and the lower wall orbottom concave, the two walls being spaced apart a short distance. The body 1 1s provided with two nipples or collars 2 and 3 which are preferably internally threaded, the one to receive a pipe- 4: plug 5, whereby the nipple or collar 3 is closed. The pipe 4 is provided with a drain cock 6. The body 1 is provided centrally of its top with a tubular projection 7 which is threaded to receive a pipe 8. A passage 9 is provided at one side of the tu u'lar projection 7 and establishes communication between the bottom of the boiler 10 and the top of the body 1. A baffle plate 11 is disposed within the body 1 about midway between the top and bottom thereof and its outer edge terminates within a short distance of the outer portion of the body. The baflle plate 11 is of concavo-convex form which corresponds to the outline of the top and bottom of the body 1. The baflie plate 11 communicates centrally with the tubular projection 7.

' The lower portion of the tubular projection 9 constitutes a by-pass through the portion 12 so that the cold water may pass therethrough from the boiler 10 into the body 1, the hot water passing from the body 1 through the tubular projection 7 and pipe 8 into the boiler 10. l

, The bottom of kitchen boilers is usually of concavo-convex form and is dis osed a short distance from the lower edge "0 the body of the boiler, thereby leaving a space. The

present invention'is designed to utilize this space, as clearly indicated in Figs. 1 and 3,- the device being constructed so as to occupy the same, thereby confining the heat and utilizing the same to the best'possible advantage. 'It is observed that sediment collecting in the outer portion of the body 1 may be drawn ofl through the pipe 4.- by opening t-he drain cock 6. Upon removing the plug 5 a suitable instrument may be introduced'through the nipple or collar 3 so as to scrape the interior of the device and remove any scale or'other' matter tendin to collect on the walls of the body or ba e.

Figs. land 2 indicate a heater 14: which may consist of a burner of any type for' utilizing gas or liquid fuel. The heater or burner is disposed centrally below the circulator so as to utilize the heat to the best possible advantage. A pipe extends into the boiler 10 to within a short distance of the hottom thereof and, is connected with the main or other source of water supply. A pipe 16 connects with the top of the boiler and communicates with the hot Water outlets. The

pipe 8 terminates within the upper portion jection 7 Int-his manner the water is ra'p-' idly heated in the upper portion of the boiler and hotwater may be obtained at any one of the outlets in a comparatively short time ,because it is not necessary to wait until all the Water in the boiler 10 is heated, since the hot water from the upper portion of the boiler passes through the pipe 16 and out through the open outlet..

The foregoing description and the draw ing have reference to whatmay be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

In the modification shown in Figs. 4 and 5 the circulator is constructed substantially in the manner hereinbefore set forth but is modified to adapt the same as a support for the boiler. A threaded boss 17 is formed upon the lower side of the circulator at a cen tral point and receives the upper end of a standard 18 which-is provided with a foot or base 19. Lugs 20 project outwardly from the circulator and are internally threaded to receive screws 21 which engage the bottom 13 of the boiler and enable the latter to be plumbed. The circulator is strengthened by a plurality of ribs 22 which are-formed on the top and extend radially thereof. Struts 23 connect the baffle 11 with the upper and lower walls of the device, thereby stiffening and strengthening the same and enabling it to sustain the weight of the boiler. The circulator operates in a manner substantially as described herein.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent 15 A c1rculator, comprismg a hollow shallow circular body provided with oflstanding apertured lugs, a depending central boss and a vertical projection containing two passages, the body being divided by a battle, one of the passagfias connecting with the space above the ba e and the other passa e connecting with the space below the ba e, and set screws mounted insaid apertured lugs.

In testimony whereof I aflix my signature in presence of two witnesses.
